[CHAMPION CONCEPT] Ger'zaz, The Void Parasite (Improvements Welcomed)

Hi everyone, this is my first attempt at a champion concept, let alone a discussion, and I wanted to share it with you guys. I looked at similar champs to try to keep it balanced, and I also wanted a second opinion from you guys. So no more delays, here it is.

Name: Ger'Zaz, the Void Parasite Race: Voidborn Primary Role: Fighter Secondary Role: Tank Place of Origin: The Void (Host body from Ionia) Friends: Enemies: Appearance: Ger'Zaz's host's appearance is that of a samurai with Ionian details added to him. His helmet has a pair of horns, one of which is broken, and his shoulders have two different coverings. His right is covered in white fur, while the other has a metal shoulder guard that is a metallic gray like the rest of his armor. The host's actual body resembles a barely visible skeleton surrounded by purple energy. He carries a standard katana that's been twisted by the Void Energy running through it, gaining a serrated edge. Ger'Zaz himself, hidden within the armor, resembles a purple snake with light blue spikes.

STATS Health: 562 Base -> 1953 at level 18 Health Regen: 6.9 Base -> 16 at level 18 Attack Damage: 60 Base -> 116 at level 18 Attack Speed: 0.644 Armor: 24.9 Base -> 84.4 at level 18 Magic Resist: 32.1 Base -> 53.4 Movement Speed: 330 Auto-Attack Damage: 125

PLAYSTYLE Ger'Zaz is designed to maximize in teamfights, the more foes he manages to catch in his attacks, the better. He's supposed to be able to focus on multiple foes, and then pick off the weakened ones as they escape. His abilities are viable in 1v1s, but is significantly more useful against multiple foes. His attacks have medium level cooldowns so you have to pick and choose the right moments to use them.

ABILITIES Passive: Restoring Host - After every 3 attacks, Ger'Zaz's next attack has a bonus 40% Life Steal.

Q: Will of Carnage - Ger'Zaz increases his Attack Speed by 5/10/15/20/25%, his next 5 auto attacks also apply 10/20/30/40/50 Magic Damage on top of his current physical damage. Casting Cost: 5% of current Health Cooldown: 15 seconds constant

W: Gashing Force - Ger'Zaz swings his blade, sending forth a horizontal wave of Void energy that deals 20/40/60/80/100 Attack Damage. The attack also grants Ger'Zaz half of the damage done in health. Casting cost: 10% of current Health Cooldown: 12/11/10/9/8

E: Grasp of the Void - Ger'Zaz opens a portal in a target location that lasts 2 seconds, foes that walk along the edge of the portal are slowed by 20/25/30/35/40%. Once the portal closes, enemies standing in the portal are stunned for 1/1.25/1.5/1.75/2 seconds. Casting cost: 15% of current Health Cooldown: 25/22/19/16/13

R: Parasitic Feeding - Ger'Zaz rushes to nearby foes and infects them with Zaz Parasites as well as dealing initial damage. For the duration of the Parasites' existence, Ger'Zaz has an increase in Attack Speed and slowly drains the foes of 20% their health each. The Attack Speed and Life Steal are directly affected by how many champs Ger'Zaz dashes to. Casting Cost: 30% of current Health Cooldown: 110/95/80

LORE (Still in work) The Void is filled with all manner of disturbing beasts, but not all of them are mighty monstrosities, nor do they all agree on plans. An example are the Zaz Parasites, who must rely on the larger Voidborn to survive. Ger'Zaz was the newest spawn of these Parasites, unique in that it had the ability to actually possess its host rather than merely feed on the host. When started calling upon the Void, the Zaz Parasites understood this as their bid for power. Ger'Zaz was sent to find the one calling the Void and possess him, so as to give the Zaz Parasites a leading role in the bid for Runeterra. However, under a unique circumstance, Ger'Zaz was spawned in entirely the wrong area, appearing within an Ionian temple rather than Icatha. Ger'Zaz explored its surroundings and found two things, the first was the body of a deceased Ionian swordsman from old, while the other was that swordsman's blade. Ger'Zaz used its possession ability to take control of the swordsman's body, and with the body reanimated, and the blade now flowing with Void energy, Ger'Zaz embarked on its quest to find the one calling its race. This quest would eventually lead it to the Institute of War.

QUOTES (Still under way, I'm not good with dialogue)

DEATH ANIMATION Ger'Zaz's host body explodes into void energy. His actual self lands among the falling armor, falling over and dying.

RECALL ANIMATION Ger'Zaz draws his sword and slashes the ground, cutting open a portal. He then tosses his sword into the air and flips, catching his sword as he lands in the portal.

I hope you guys like :D I'll also be looking forward to any advice on how to improve this character. I might draw some concept art if he gets good reviews.
